Bieber captioned the picture "What more can they say" followed by a crown icon, presumably a reference to Jackson's "King of Pop" nickname.

The picture is the first comment or social media post from Bieber since Thursday's arrest.

Jackson's picture was taken following his January 2004 arraignment on child molestation charges. The King of Pop pled not guilty and then climbed on top of an SUV outside the Santa Barbara County Courthouse. Jackson was later found not guilty of all charges.

Bieber's manager, Scooter Braun, and father Jeremy have also spoken out via Twitter.

Braun posted the following two messages, expressing support for his client, but also saying he would "act in the manner of someone who truly cares."

@justinbieber love you and i will act in the manner of someone who truly cares. that is all I have to say. thanks for all those concerned
